How do I do this problem

Answer:


Step-by-step explanation:

It is really quite simple, there are going to be three answers you can get Homozygous Dominant (TT or two capitol letters), Heterozygous (Tt one capitol and one lower case, and Homozygous Recessive (tt or two lowercase letters). To find the specific genotype or phenotype, you look at the letters and compare them to the chart. For the punnett square, you use the two parents genotypes, and put one on each of two sides on the square and take one letter from each side of the square and put them together. The probability is just how many of each is that specific phenotype, but you will want to us either ratios or percents. I hope this is helpful.

Which of the following constants can be added to x2 - 3x to form a perfect square trinomail?
serious [3.7K]

The constant that can be added to x^2 - 3x to form a perfect square trinomial is 2\frac{1}{4}

The given expression is

x^2 - 3x

To form a perfect square trinomial

(a-b)^2 =a^2-2ab+b^2

The given expression is

x^2 - 3x

first we have to add a constant term with it

x^2 - 3x + z

By comparing the given expression and the perfect square trinomial

a^2 =x^2

a = x

Similarly

-2ab = 3x

where know a =x

Then,

-2b = 3

b = -3/2

Similarly

b^2 = z

(\frac{-3}{2})^2 = z

9/4 = z

Convert the simple fraction to mixed fraction

9/4 = 2\frac{1}{4}

Hence, the constant that can be added to x^2 - 3x to form a perfect square trinomial is 2\frac{1}{4}

The complete question is :

Which of the following constants can be added to x2 - 3x to form a perfect square trinomial?

1\frac{1}{2},2\frac{1}{4} and 4\frac{1}{2}

Order the following in descending order<br> -3/4, 1/8, -0.735, 7/8, 1/80, 0.056
Vilka [71]
If you would like to order the following values in descending order, you can do this using the following steps:

- 3/4 = - 0.75
1/8 = 0.125
- 0.735
7/8 = 0.875
1/80 = 0.0125
0.056

The result is: 7/8, 1/8, 0.056, 1/80, - 0.735, -0.75.
